I haven't been able to get my phosphate level up to speed. I am dosing EI on my 150 CO2 injected tank. I just started the CO2 and EI last week after a few months of low tech. I raised the amount of KH2P04 to 1 tsp every three days from 3/8 tsp, but just started that this week. So far my level (per Salifert test kit) is only 1ppm. Salifert is normally a very reliable kit so I assume it is correct. Should I up my dosage amount or is there something else I am missing? I'm attempting to get it up over 3ppm at minimum.

Thanks

I think your levels are fine; just keep dosing per EI (or as you did, increasing the phosphates just a bit).

Also, you might as well make some calibration solutions for your Salifert test kit.
